THERE are three formula for for calculating all this
mean binomial distribution=n*p*q
standard deviation of binomial distribution =square root(n*P*q)
variance of the binomial distribution= standard deviation square
p+q=1;
q=1-p=1-0.45=0.55;



now to come to the problem
mean=129*0.45=58.05
standard deviation=5.65044;
varince=31.925
